Heres a link to A Jane Plant book.
Worth a read. Thought provoking.
Some europeans are reported as having developed a genetic adaptation to dairy products.
The Icelanders I beleive are often used as a genetic database because of a degree of historic isolation. Do they have the european gene for dairy metabolism?
One might expect them to be high fish eaters.
More research required.

Interesting.
Additional thought if milk is poorly tolerated could it add to low level body inflamation, which in the presence of high six could fuel low level body inflamation, gut inflamation ( plus pyroli. plus artery furring etc etc) leading to a self fuelling cycle weakening the bodies defenses etc.
